All the bishops turn pale and cry (7)
I believe the answer is:
prelacy
'all the bishops' is the definition.
I can't tell whether this defines the answer.
'turn pale and cry' is the wordplay.
'turn' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'pale' after 'cry' is 'crypale'.
'crypale' with letters rearranged gives 'PRELACY'.
Can you help me to learn more?
(Other definitions for prelacy that I've seen before include "Church government" , "Bishops" , "Clergymen" .)
